氨丙基三乙氧基硅烷和氨丙基膦酸酯修饰的碳纳米管是通过氟化碳纳米管（F-CNT）与3-氨丙基三乙氧基硅烷或3-氨丙基膦酸试剂在120℃下以吡啶作为碱催化剂反应制备的。这些功能化碳纳米管、APTES-CNTs, 1 和 APPA-CNTs, 2 通过透射电子显微镜 (TEM)、红外光谱 (IR) 和热重分析 (TGA) 进行了表征。这些功能化碳纳米管 (0.1%) 在二氧化硅中的均匀分散也是通过溶胶-凝胶处理实现的。 TEM 证实功能化 CNT 在二氧化硅中均匀分散。
Aminopropyltriethoxysilane and aminopropyl-phosphonic ester modified carbon nanotubes were prepared by reacting fluorinated carbon nanotubes (F-CNTs) with the 3-aminopropyltriethoxysilane or 3-aminopropyl-phosphonic acid reagents at 120 °C temperature, using pyridine as the base catalyst. These functionalized carbon nanotubes, APTES-CNTs, 1, and APPA-CNTs, 2, were characterized by transmission electron microscopy (TEM), infrared spectroscopy (IR), and thermogravimetric analysis (TGA). The homogeneous dispersion of these functionalized CNTs (0.1%) in silica were also accomplished by sol–gel processing. The TEM confirmed uniform dispersion of the functionalized CNT in silica.
